Bill Y. James, Miami, kla., assignor of one-half Application July 2, 1945, Serial No. 602,704" 4 Claims. (Cl. 22916) This invention relates to jackets or wrappings for cartons and has for a primary aim to provide a collapsible pre-i'ormed package jacket capable of being folded to a flat condition for shipment, storage and handling prior to its application to One of the important aims of my invention is to provide a package jacket of the aforementioned character constructed through the employment of a blank formed from sheet material and supplied with a number of specially disposed lines of fold and lines of bend, all cooperating to allow the quick and inexpensive manufacture of a preformed jacket that will collapse into a compact fiat unit when not operatively extended; that will produce a jacket having strong walls of laminated material where strength is most needed and that is capable of being expeditiously applied to a package for sealing therearound.

Other objects of the invention will appear during the course of the following specification referring to the accompanying drawing wherein:

Fig. 1 is aplan view of the'blank from which the collapsible pre-formed package jacket embodying my invention is capable of being produced.

Fig. 2 is a plan view of the folded jacket as it appear in a condition for shipment or storage, and

Fig. 3 is a perspective view of the pre-formed package jacket showing the same in an extended condition ready to receive the package for which it is especially dimensioned.

The packagejacket is preferably made of sheet material such as conventional wrapping paper but since the gift package art has become important it has developed a need for neat-wrappings of relatively expensive sheet material and therefore, since this jacket may completely encase a package with a minimum amount of waste, it is advantageous to construct fancy wrappings in a man er contemplated by the invention.

Packing box sizes are being standardized to a considerable degree an when constructing the pre-formed package jacket as illustrated in' the accompanying drawing, regard for said package the end that the jacket may be of a size to snugly fit the boxes or article with which the jacket is to be associated.

The blank that is generally designated by the numeral Ill comprises a number of set-off areas that later become the various walls of the formed and distended jacket. Blank It), therefore, in- "eludes a side wall l2, an end wall l4, an end wall l6 and a side wall which is opposite to side wall I2 when the jacket is formed, as shown in Fig. 3. This last mentioned side wall is made of sections l8 disposed at opposite edges of blank l0. Each the top wall and bottom section l8 has a portion of reduced width 20 and a portion of relatively greater width 22. For clearness of description, the walls which close the open end of the tubular body which includes side wall l2, end walls l4 and I6 and the side wall composed of sections I 8 are herein designated as wall respectively. The bottom wall is formed of a number of over-lapping sections 24 and over-lapping extensions 25. The outermost layer of this bottom wall is a flap 28 having a tongue 30 along'the free end thereof and set oil by a line of bend 32. The top wall comprises a number of superimposed layers of the material when the jacket is closed around a package and in blank form these layers comprise sections 34 and an area 36 from which is extended flap 38. A line of bend 40 extends completely across the blank ID from one edge thereof tothe other and sets oii sections 34 and areas 36 from the remaining portion of the blank. It is this separating line of bend that becomes the edge of the distended dition shown in Fig. 3. Flap 38 has two transverse lines of bend 42 and 44 extending thereacross, the former being used when the jacket is in the condition shown in Fig. 2, while the latter (44) sets oif that portion of flap 38 which depends along the side wall composed of sections it to close the notch 48 provided between relative- 1y narrow portions 20. A line of bend 46 extend-' ing entirely across blank ill at the base of flap 28 becomes the line of meeting between the laminated bottom wall of the jacket and the two end and two side walls. Other lines of bend about which the material fold is in a direction the same as it is folded about lines of bend 40, 42, 44 and 46 are designated by the numerals 48 and 55, both serving to create a foldable part of the material that establishes the bottom wall. Line of bend 52 and 54 separate sections 34 and areas 36 and are extended across the blank to line of bend 46 as is clearly shown in Fig. 1. This extended portion of line of bend 54 separates end wall l6 and section l8 while the similar line of bend 52 separates end wall I4 and the opposite section 48. Another line of fold 55 crossing line of fold 40 and reaching the edge of blank 10 from which flap 38 is projected establishes an edge of the jacket and sets ofl? end walls l4 and I6 from side wall l2. The lines of fold designated by double dotted lines and numbered 56 flex when the jackjacket when it is in the connotch in the upper part et is being formed as will be later set forth. The lines of fold B and 60 likewise flex to form the top well. After the blank has been scored to create these lines of bend and lines of'fold and also to establish lines of flexure 62, the jacket is assembled by bringing to the marginal free edges of sections l8 where the adhesive 64 on one section It adheres to the other section l8 to, create a tubular body. Thereupon'sections 24 are turned inwardly along a portion of line of bend 46 to have their ends overlapped where the adhesive 64 secures the same together. Extensions 28 are turned in along that portion of line of bend 45 at their bases and the adhesive 66 on the free marginal edge of one extension serves to secure these two over-lapped extensions in place across the bottom of the jacket to form one or the layers of the bottom wall. Flap 28 is next turned in along that portion of line of bend 46 along its base and tongue 30 is turned upwardly against the outer faces of sections it along line of bend 32. When this flap and tongue 38 and 32 are so moved to complete the formation of the bottom wall, the adhesive 68 shown by the shaded lines of one serves to anchor the flap 28 in place to establish the smooth final outer layer of th substantially triple thickness bottom wall.

At this juncture the form of the jacket is as shown in Fig. '3 and may be folded to a flat condition as shown in Fig. 2 for stacking, storage and shipment. When the package, not here shown, is to be slipped into the jacket, it is distended and slipped into the top end whereupon sections 34 and areas 36 are folded inwardly over the upper end of the package along line of bend 40. The lines of bend 52 and 54 and lines of fold 58 and 6|] fiex, as clearly shown in Fig. 3, to overlie the package contained in the jacket whereupon flap 34 is folded down around a portion of the line or bend 40 and thence downwardly along the outer faces of portions of reduced width 20 to close notch 48. Adhesive alon the marginal edge of flap 38 holds the said flap in place and a smooth reenforced complete jacket results. Notch 48 gives clearance for manipulating the jacket and package as the two are being brought together in order that a snug fit may be established.

Having thus described my invention what I claim as new and desire to be secured by Letters Patent is:
